My First Solargraph

Today, after six months I opened the solargraph. The can was still intact and the photopaper was well preserved. The paper was humid and still fixed against the wall of the can. Looking at the picture you will see some interesting aspects. In the front (at the bottom of the picture) you see my garden with the trapoline in the middle and the trees some further.

Also the top of the sunpaths is not captured on the picture. On the inverted pictures the many black band show the poor spring without "sun".

The Moon and the Effect of Focal Length

Ever curious what the effect is of Focal Length. Attached photo shows the moon with different focal length. Background picture shows the moon with focal length 3000mm, the smaller ones 400mm and 200mm. All pictures taken with Nikon D60.
